Brute LFO

A powerful low frequency oscillator that modulates your analog gear.

If you have a hardware synth that allows you to use external gear to modulate the pitch, the filter, or any other parameter, just plug the Brute LFO into the CV in and start playing.

“ Hooked it up to my EMS Synthi and its pretty amazing indeed…it works! ”

“ Bought the app - works perfectly with my mini brute! Great work! ”

Two LFOs

The two main LFOs can be controlled using the elements in the top half of the screen. The big knob in he middle sets the rate of both the LFOs. Additionally you can change the waveforms of the LFOs, detune LFO 2 and change its phase.

Features

A third LFO can be used to modulate the frequency of the two main LFOs. You can change its waveform, rate and amount. The optional Brute Mode destroys the pretty LFO signal by adding cross modulation and distortion. It produces a harsh and unpredictable sound.

Specs

The iPhone can produce voltages in the range of about +/- 1V. You have to amplify the signal if you need +/- 5V.
The slowest possible rate of the LFO is at about 0.5Hz, the fastest rate is 150Hz.
